Haemosporidian parasite prevalence, parasitemia, and diversity in three resident bird species at a shrubland dominated landscape of the Mexican highland plateau

Table 1 Diagnosis and estimation of haemosporidian parasite true prevalence in three bird species

Species	n	Positives		Prevalence (%)	\( \overline{x} \) parasites/100 fields
Species	n	PCR	M	Prevalence (%)	\( \overline{x} \) parasites/100 fields
Cactus wren	16	0	0	na	0
Canyon towhee	40	17	19	47.5	22.8 (3.6)
House finch	106	43	46	44.3	70.3 (12.3)

Number of bird blood samples from the “Ixtlera” region of northern San Luis Potosi yielding positive parasitism by haemosporidians. Estimates were obtained through PCR and observations of 100 fields (100×) through microscopy (M). n = total number of samples analysed by species. Prevalence = % of all samples from species yielding positive parasitemia. Average number of parasites found in 100 fields (100×) is reported (standard errors are presented in parenthesis)
