We are no strangers to disease coryza<\/em> or what is familiarly known as \u201csnot". Disease coryza<\/em> still get into the top 10 ranking of diseases that attack chickens, both in chickens layer<\/em> or broiler<\/em> over the past 3 years. This shows that overcoming coryza<\/em> not easy to do.<\/p>\n\n\n\n

Why case coryza<\/em> still stubborn and hard to control? What about your own experience? Is that so?<\/p>\n\n\n\n

Current Cases of Coryza<\/em> Now<\/strong><\/p>\n\n\n\n

Diseases caused by bacteria Avibacterium paragalinarum<\/em> (Av. Paragalinarum<\/em>) this predilection location is primarily in the infraorbital sinus. Bacteria Av. paragallinarum<\/em> causes coryza<\/em> it is divided into several serovars. Based on the method page<\/em>, dibagi menjadi serovar A, B, dan C. While the method kume<\/em> membagi lebih detail lagi menjadi A1, A2, A3, A4, B1, C1, C2, C3 dan C4. Diantara serovar tersebut, tidak ada proteksi silang antar serovar A, B, C namun terdapat proteksi silang yang baik diantara serotipe pada serovar A (A1, A2, A3, A4) dan proteksi silang variatif diantara serotipe pada serovar C (C1, C2, C3, C4).<\/p>\n\n\n\n

Teams Research and Development<\/em> Medion has done mapping<\/em> bacterial causes coryza<\/em> in Indonesia. Based on the isolate data collected by Medion, currently the bacteria Av. paragallinarum<\/em> found in Indonesia, it belongs to serotypes A1, C1 and C4. Especially the dominant serotype C4 is found and has been widely spread in several regions in Indonesia such as Bandung, Banjarmasin, Jambi, Kendal, Samarinda, Semarang, and Sukabumi.<\/p>\n\n\n\n

Based on data collected by the team Technical Education and Consultation<\/em> (TEC) Medion, a case in chickens broiler<\/em>, the disease ranked 6th in the period from January to June 2021. As for the occurrence of cases coryza<\/em> on chicken layer <\/em>it ranks 1st in the sense that its occurrence is worth being wary of.<\/p>\n\n\n\n

When viewed from the data in Graph 1 is known that the case coryza<\/em> the trend increases in the rainy season and the transition of weather (transition). Especially on farm<\/em> layer<\/em>, October 2020 experienced an increase until the turn of 2021 entered the third month to be the highest peak in case incidence. So farmers need to be aware of the increase in cases coryza<\/em> in wet seasons or transitions that cause chickens to experience stress so that the condition of chickens decreases. The humid conditions of the cage environment also favor bacteria coryza<\/em> growing quite rapidly. Case occurrence coryza<\/em> triggered predisposing factors, such as interference from the home environment, nutritional problems, vaccination treatment as well as various diseases that cause immunosuppressive.<\/p>\n\n\n\n

Poultry\u00a0layer<\/em>\u00a0or\u00a0broiler<\/em>\u00a0both are susceptible to attack, but in 2021 the number of reported cases in chickens\u00a0layer<\/em>\u00a0higher than chicken\u00a0broiler<\/em>. This is because the life span of chickens\u00a0layer<\/em>\u00a0longer so that the risk of exposure to the disease is higher and aggravated by ventilation problems and poor environment. Predisposing factors that can provoke and aggravate respiratory diseases such as\u00a0coryza<\/em>\u00a0among other things, poor air quality, lack of ventilation and poor air circulation result in reduced intake of o\u2082 needed by chickens. Erratic weather conditions will cause the chicken to be stressed so that the condition and endurance of the chicken's body to decrease. When the condition of the chicken's body decreases, the disease will more easily enter and attack the chicken's body including\u00a0coryza<\/em>. Therefore, chicken\u00a0layer<\/em>\u00a0requires protection with a long duration of immunity. Occurrence of infection\u00a0coryza\u00a0<\/em>it can be recurrent and always appear throughout the year, therefore\u00a0coryza\u00a0<\/em>threatens almost at any age chickens\u00a0broiler<\/em>\u00a0and\u00a0layer<\/em>. Especially with chicken\u00a0layer\u00a0<\/em>widely implement maintenance system\u00a0multi age farming<\/em>\u00a0(many ages), where if there are chickens that have recovered from the attack\u00a0coryza<\/em>\u00a0will act as\u00a0carrier<\/em>\u00a0(carriers) and can infect other healthy chickens that are in one population or one cage with chickens\u00a0carrier<\/em>\u00a0the.<\/p>\n\n\n\n

Factor\u00a0litter<\/em>\/ wet husks result in increased humidity conditions in the cage and high ammonia levels can be inhaled by chickens. This results in epithelial cells (mucosa) in the upper respiratory tract experiencing irritation. These cells are an early defense mechanism because they are able to produce mucus (mucus) and consist of cilia to repel incoming infectious agents. Irritation that is not handled properly will create bacteria\u00a0coryza<\/em>\u00a0managed to enter and stick in the sinuses of the nose, then cause even more severe infection.<\/p>\n\n\n\n

Routes Of Transmission Coryza<\/em> Noteworthy<\/strong><\/p>\n\n\n\n

Coryza<\/em> attacking chickens through feed media, drinking water, and air contaminated with exudate \/ chicken nasal discharge containing bacteria Av. paragallinarum<\/em>, or direct contact with the first chicken attacked coryza<\/em>. The exudate that comes out of the nose is the medium of transmission coryza<\/em> which is very effective between chickens, especially for cages with drinking places paralon. Often found in the field, cases coryza<\/em> it becomes repetitive and persistent, even more so if there is no selection. Other factors high chance of cases coryza<\/em> especially in the rainy season because in addition to bacteria E. Coli infection<\/em> commonly transmitted by water, bacteria coryza<\/em> it can also spread quickly through abundant water media in the rainy season.<\/p>\n\n\n\n

Bacteria Av. Paragalinarum <\/em>enter through the mouth or nose, then it will enter and multiply in the nasal sinuses (sinus infraorbitalis) with an incubation period of 1-3 days followed by the rapid appearance of clinical symptoms. Outbreak<\/em> coryza<\/em> lasts for 4-12 weeks (in chickens layer<\/em>) or 6-14 days (in chickens broiler<\/em>) depends on the type of serovar, the number of bacteria in the body of the chicken or the environment of the cage, and the presence or absence of secondary infection.<\/p>\n\n\n\n

As we know the occurrence of cases coryza<\/em> this will cause some disadvantages as follows :<\/p>\n\n\n\n
